You need both ideally... Sent from my iPhone using Tapatalk

The Sonoff will be you best bet because it is real time, however it shows no trend (history). The AirComfort is Bluetooth so you can only ‘dump’ what’s happened before when you phone is within range. Sent from my iPhone using Tapatalk

I’ve set it to 23C on cool, with fan at medium. The lights in the tents push it up on their own to around 25 / 26. When the light go off the ac stays at 23 and in theory, the canopy should follow suit. I believe this will give me a very smooth transition in temperatures and probably humidity since the ac will always be on... at 23C at any rate. My lights are out now till 5pm so I’ll check and post later how it went. I just want to stabilise the environment! Sent from my iPhone using Tapatalk

This is all you need Sent from my iPhone using Tapatalk

I do t mind the questions, mine will be about the plants etc [emoji85][emoji1787] Sent from my iPhone using Tapatalk

No need for Zigbee bridge. Just the TH16, the temp and humidity sensor (there are two options, you don’t want the waterproof temp one, that’s for beer and geysers). Then that will connect to your WiFi. Your app connects to the Sonoff server and your WiFi does the same. Awesome. There are you tube videos. Sent from my iPhone using Tapatalk

Yes, that’s a switch only. The TH has a sensor and can also just be a switch. Make sure your ac will turn on with it, some ac units don’t return to previous state on power return... Sent from my iPhone using Tapatalk

That’s the aircon turning on and off as I said earlier. A sealed tent is less susceptible to that, but in a open room or open tents it does that. Another argument for having a suitably sized ac in your space... a smaller ac might be smoother. Sent from my iPhone using Tapatalk

Lol SoloKush are you into conspiracy theories? [emoji12] Look up the SonoffTH16 off takealot. That’s WiFi based, then the images above are from the AirComfort app, that’s unfortunately only Bluetooth, although you can get a bridge device apparently. Sent from my iPhone using Tapatalk

Getting the lights on dialled in... Sent from my iPhone using Tapatalk

Another thing I’ve noticed with the ac, it seems better to find a sweet spot for 3 parameters, namely outside conditions, lights on and lights off. (Besides where the plants are in terms of their seasonal humidity needs) So I just leave it on all the time and adjust the temperature and fan speed only. If you allow it to turn itself on and off with its own sensor, you tend to get ‘jaggered’ temp and humidity traces. Sent from my iPhone using Tapatalk

Imagine that! But was that not because of the cold outside vs the warmth inside? Ie normal condensation? Or was you RH thru the roof? Sent from my iPhone using Tapatalk

I’m certain it will almost be overkill. My 18000 is doing a space 4 times that and even on the hottest days, doesn’t flinch. I think the closed system helps. Sent from my iPhone using Tapatalk

I’m running 2 dehumidifiers and managing to keep humidity in the room between 50 and 60%. I’d like to see it lower but there is a lot of transpiration from the ladies, I’ve never had such thirsty plants before! So to combat it I’m having to run the ac lowish, they seem to dehumidify better at lower temp settings (“cool”). This in turn lowers the tent temps but that can be controlled to an extent with tent sides restricting air flow a bit so the lights warm the air in the tent space. Problem comes in when lights go off, humidity spikes and tent sides must come down. Toying with the idea of using small fan heaters in the tents during lights out to help dry the air. So yeah, dialling it all in slowly, it’s a mission. Sent from my iPhone using Tapatalk

SoloKush my controller also came with two seemingly sh&tty plastic washers. I think one is a spare, at any rate I only used one. When I turned on the gas there was an audible leak. After puzzling a bit I decided to lick the washer and that sealed it properly. I meant to go to Afrox to possibly find a better washer but I suspect they all like that, I think it’s Teflon. [emoji2369] My Mars are 450mm above canopy and the Migro 160mm. (Well that’s what manufacturer specify) Sent from my iPhone using Tapatalk

@SoloKush for the most part my tents remain open on at least 2 sides. This is because the humidity gets out of hand when the lights go out. Each tent has a carbon filter and an AC Infinity T8 setup in the usual way, however they extract to the room and not the outside. Each T8 has a temp/ humidity probe inside its respective tent; and they will turn on and off based on those settings (max and min humidity and temp). They serve really to assist air movement and to scrub odour from the room. My room only vents when the door is opened, or left open for a bit due to high CO2 levels. The split a/c has the job of cooling the air from the T8 in lines and the dehumidifiers, and it also dries the air. Sent from my iPhone using Tapatalk

Thanks Prom, it’s actually looking a bit messy as things have been added to the room after the initial setup. I suppose it might have something to do with experience, you never know how things pan out in the country, what opportunities may arise. Might help to be prepared, who knows? So for now I’ll keep on keeping on, if I get the sh*ts with CO2 I’ll bin it. If not I might exploit it later.... Appreciate your candid input, I’ll be knocking on your door for more [emoji6] Peace Sent from my iPhone using Tapatalk

I’ll look into getting a Mars 3000 at some point to add to the SP250’s, can’t add to the Migro. Main reason for the CO2 was to maintain a closed system, anything else is a bonus. Here are some pics Sent from my iPhone using Tapatalk

Having said that the tents are mostly open, I pretty much just use the sides for air movement control and the tent structure to hang things off. I find that in my sealed room setup, the humidity spikes in a closed tent after lights out so with it being open, the increased volume of air has a higher capacity for holding moisture better. I’ll post a picture later. Sent from my iPhone using Tapatalk

Sorry, good point. In feet. Do they make 5mx 5m tents? So it’s a 1,5m by 1,5m and a 1,2 by 1,2m. Sent from my iPhone using Tapatalk

Hey Prom, I’ve just read and responded on that other CO2 post. Thanks so much for all the knowledge. I’m trying really hard to have a near as dammit automated setup so it’s going to have teething problems. All good tho. Sent from my iPhone using Tapatalk

Hey Solokush and Prom Just stumbled on this post again, I’m not getting notifications, guess I should subscribe to it? I bought a controller like the one in my picture, probably 3 weeks ago. They must have sold out. Initially I just wanted a co2 meter but for an extra 1k odd I got the controller. Brilliant piece of kit, and less than half the price of the same type of device from the hydro shops... So on my setup, it’s 3 small interlinked rooms, like small workshops. The first room just fits a 5x5, the second just fits a 4x4 and the last one is where I keep the nutes etc. I will probably not use tents next grow, rather just the ladies on a raised table. I have the following: 2 x AC Infinity 8” fans which used to extract outside, one for each tent, each with a mother of a carbon filter (they now scrub the inside recycled air so little odour leaks out) 1 x 18,000 inverter btu a/c with Sensibo control; 2 x Meaco 20l Dehumidifiers run 24/7 1 x CO2 controller with regulator from a hydro shop. The CO2 line is T’d off, one to each tent, run to the back of oscillating fans high up; 7 x fans, some small oscillating, some floor standing 2 x Autopot systems with air domes; 1 x Migro Aray 720 in 5x5 2 x Mars SP250 in 4x4 3 x Sonoff devices to monitor Temp and Humidity in room and 2 tents. 1 x 3k Inverter on 400a/h gel batteries, this runs 1/2 lights and all fans/ extraction for around 3hrs. My intention was never to have a sealed setup, it just evolved that way, mainly because of a need to exclude outside humidity and to recycle ac air. I must say there is almost no odour and zero noise outside the room. It also eliminates any weird stuff getting in like pollen, bugs, spores etc. The CO2 came for the same reason as your idea, to keep the plants ok in a sealed setup and to exploit summer heat next year, hopefully. I don’t think the air flow rate is that critical because in such a small space it reaches your set value and maintains it there really well. The CO2 takes forever to dissipate / get consumed so at this stage I do think it is very economical once the kit is purchased. The gas bottle I got was a frikkin 100kg beast, almost as tall as me... next time I’ll go for a third of that!! You still need to hire the co2 bottle every month which is a bitch. Prom’s warning about the dangers of CO2 are well heeded, I will definitely be making sure there is ample ventilation when I work in there from now on! Anyway, it’s a steep learning curve for me, happy to share ideas etc. Peace Sent from my iPhone using Tapatalk

Thanks Prom, I appreciate the help. I am running CO2, only at 800ppm, so I have been running higher than normal temps. It’s a bit of hit and miss this grow. Started this grow in summer and the temps plus humidity were crazy. Bought better extractor fans but they caused more humidity to enter the room and the dehumidifiers were not coping. So I got a new split ac which helped but still all that cooled dry air was being sucked outside. So I tried running the outlets into the room itself, like a closed sealed system. This worked surprisingly well but now the available co2 to the plants would be used up. I bought a co2 controller just to keep tabs on the CO2 levels, and it turned out I’d need to open the room up a bit every day to replenish Co2. Not a problem unless I went away for 3 or 4 days. So I got a co2 reg and bottle, not really to push the CO2 grow, but mainly to keep it good for the plants, around 500ppm. Slowly I increased it along with slightly higher temps. My aim next summer is to run my lights during the day and make use of the co2 to allow high temps, and save on the amount of ac power I’m using. This will also allow a natural temperature drop during the evening, so run 18/6 from 06h00 till midnight or similar. The whole thing is a balancing act as you know. I think my problem plant wasn’t getting enough air over her canopy, a bit of a hot spot in the tent corner. Sent from my iPhone using Tapatalk

Hi Prom, I suspected either heat stress or both heat stress and my Autopot res running dry as a combo issue. I have LED’s which ought to be 45cm away but mine are 35cm. Maybe this specific lady didn’t dig it, the other 3 are fine. Might also be a dead spot in the tent where the oscillating fans don’t reach. I went away for 3 days so never checked daily. Should I trim those leaves off or just leave them be? Sent from my iPhone using Tapatalk

First 3 pics are from one of four Blue Amnesia Auto (Dynafem). Last pic is the same strain, different plant, no issues. Any ideas what this could be? Sent from my iPhone using Tapatalk
